Charging Modes with Solar - iEV Solar Smart EV Charger

The iEV 22kW Solar Smart Charger offers three charging modes, giving EV owners the flexibility to prioritize charging speed, continuous charging, or solar energy.

1. FAST Mode — Charge as Quickly as Possible

FAST Mode charges the EV at the maximum charging current the user sets. It does not prioritize solar or grid power; instead, it uses available power sources to deliver the selected charging current.

Best for: When you need to charge your EV quickly.

2. ECO Mode — Solar First, Grid Support

ECO Mode uses as much available solar power as possible, using grid power when needed to maintain the minimum 6 A charging current required by most car manufacturers.

For example:

2 A solar + 4 A grid = 6 A charging
5 A solar + 1 A grid = 6 A charging
16 A solar + 0 A grid = 16 A charging

Best for: Everyday charging while maximizing solar self-consumption.

3. ECO+ Mode — Maximum Solar Priority

ECO+ Mode allows the user to set the minimum grid current from 0–5 A, controlling how much grid power can be used before charging starts.

Scenario 1: Minimum grid current set to 0 A. This provides solar-only charging:

2 A solar + 0 A grid → No charging
6 A solar + 0 A grid → 6 A charging
10 A solar + 0 A grid → 10 A charging

Scenario 2: Minimum grid current set to 4 A
1 A solar + 4 A grid → No charging
3 A solar + 3 A grid → 6 A charging
10 A solar + 0 A grid → 10 A charging

Best for: Users who want greater control over solar utilization and grid consumption.

FAST = Charge fast.
ECO = Keep charging with solar first.
ECO+ = Control grid use and prioritize solar.
